2 Claims.

. This invention generally relates to a means for mounting a sink of the fiatrim type within an openin in a drain board, cabinet top, or, other supporting structure.

Variousmeans have been provided in the past for mounting sinks .of the flat rim type in supporting structures. Many of them have comprised a moulding with a T-shaped cross-section that extends around the sink rim, in combination with a clampthat carries-a tightenin means for engaging with either thesink or the drain board. My invention also relatesto this general type-of mountingmeans, that is, one havin a moulding with a .T-shaped cross-section and a clamp, but my invention differs from those previously known in that the means for tightening the clamp memher is carried by the T-shaped moulding itself. This is an advantage because it simplifies the construction of the clamping member and results in an overall construction that is simple to use. The clamping members are items in the mounting means as a Whole that are often misplaced and permanently lost. A reduction in their cost is then desirable because their loss or misplacement is not of such a consequence. The simpler clamping member is also easier to manipulate during installation.

According to my invention, I mount a flat sink rim in an openin of a supporting structure with moulding having a generally T-shaped crosssection, the top of which overlies adjacent edges of the sink and of the supportin structure and the leg of which extends between the adjacent edges of the sink and of the supporting structure. According to my invention, the leg portion of the mouldingis formed with longitudinally spaced apart openings through which a clamping member can be inserted. The clampin member and openings are formed relative in size to each other so that the clamping member has free movement within the opening towards or away from the top of the T cross-section of the moulding frame. The clamping member within the opening is tightened against the under side of the sink'rim and the under side of the supporting structure, in use, by means of a tightenin screw or its equivalent that is carried by or mounted on the moulding itself. The invention will be clearly understood after reference to the followin detailed specification taken in conjunction with the drawings.

In the drawings:

Figure 1 is a sectional view illustrating the means for mountinga fiat rimmed sink within a supporting structure according to the present invention.

Figure2 is a broken. view along the line- 22, of Figure 1 illustrating the two spaced apart clamping brackets.

Figure 3 is an exploded view illustrating; the component parts ofxa means for mounting a sink rim accordin to the present invention.

Figure 4 is a perspective view illustrating a sink mounted within a-drain board according to the present invention.

Referring to the drawingsthe numeral I0 indicates a sink of the fiat rim-type, mounted on thedrain board II of a cabinet [2.

My invention relates to a means for mountin the sink H3 on the drain board II andit comprises a moulding I3 adapted to extend around the entire outer edge of the sink as illustrated in Figure. 4, and having a T-shaped cross-section as illustrated in Figure 1 and Figure 3. In use, the top of the T-shaped moulding overlies adjacent edges of the drain board II and of the flat rim I4 of the sink II] as illustrated in Figure 1 of the drawings. The moulding, of course, continues entirely around the sink as illustrated in Figure 4 of the drawings. The leg of the T- shaped cross-section of the moulding I3 extends downwardly between the edge of the drain board I I and of the rim I4, also as illustrated in Figure l of the drawings.

According to my invention, the leg portion of the moulding I3 is formed with longitudinally spaced apart openings I5 which are designed in use to receive clamping members I6, one end of which is designed to engage with the sink rim and the other end of which is designed to engage with the drain board. The height of the openings I5 is such that the clamping members It can move within the openings I5 towards or away from the top of the moulding. Openings I5 are preferably six inches to ten inches apart, but can be located as close together or as far apart as it is desired to have the clamping members It for the sink.

A clamp tightening member I! is carried by the leg portion of the moulding l3 and, in the embodiment of the invention shown, comprises a screw I! that threads into a passage I8 that communicates with the bottom of the opening I5 and the bottom edge of the leg portion of the moulding I3. It will be apparent that by tightening or loosening the thumb screw I'I against a clamping member I6 that is inserted through the opening I5 that the clamping member can be caused to move within openings I5 towards or against the top portion of the T-shaped moulding or into or out of clamping engagement with the bottom of the drain board I I and sink rim I4.

To accommodate the difference in thickness of the drain board H and the flat sink rim M, I provide an L-shaped clamping member It, the base of which is designed to engage with the under side of the sink rim and the leg portion of which is designed to engage with the under side or the drain board under the tightening force of the screw 11.

Embodiments of my invention other than the one shown will be apparent to those skilled in the art and it is not my intention that my claims should be limited thereto. The essence of my invention is the provision of a means for mounting a flat rim sink employing a rim moulding having a T-shaped cross-section in which the clamp tightening means are carried by the moulding itself and engage with a clamp that is inserted through an enlarged opening in the leg portion of the T-shaped moulding.

What I claim as my invention is:

1. In a device for mounting a sink in an opening in a supporting structure, a moulding having a T-shaped cross-section, the top of said T being adapted to overlie adjacent edges or" the sink rim and supporting structure, the leg of said T being adapted to extend therebetween. a clamping member having one end for engaging the under side of a sink supporting structure and its other end for engaging the under side of a sink rim, an adjustable clamping member sustaining and tightening means carried by the leg of said T moulding, the upper end thereof being adapted for operative engagement with said clamping member between the ends of the latter member to sustain it, said leg of said "f shaped moulding being formed with an opening, said clamping member sustaining and tighten ing means comprising a bolt, the leg of said T- shaped moulding being formed with a threaded hole for said bolt extending from the lower edge of said leg to said opening, said bolt being threaded into said threaded hole from the bottom edge of said leg whereby the free end thereof enters said opening, said opening being adapted to receive said clamping member therethrough with the ends of the latter. underlying opposite sides of the top of said Tsection and having a depth References Cited in the file of this patent UNITED STATES PATENTS Number Name Date 2,158,467 Madsen May 16, 1939 2,280,094 Madsen Apr. 21, 1942 2,502,553 Ball Apr. 4, 1950 2,503,982 Willis Apr. 11, 1950 2,582,816 Bonnell Jan. 15, 1952 2,584,581 Harris Feb. 5, 1952
